In Generating and Using Electricity, we find out how electricity is generated from many sources, including waves, wind, and the Sun. Learn about electric charge, cells and batteries, generators, and electric motors. We see how power plants distribute electricity, how we get usable voltages in our homes, and how low-energy bulbs can reduce our energy consumption. And we discover cutting-edge technologies, such as plastic that conducts electricity, microbial fuel cells, and generators that run at –196ºC (–321ºF).
